This sleek leather wallet has a hidden iPhone charger

The designers of the Nomad lent me one of their battery-hiding wallets, and I've been using it for the past week. The wallet I have is the larger bifold style, which costs $149.95 and has slots for six cards as well as cash. Nomad also makes a smaller "Slim" version for $119.95. Both are genuine leather and contain a 2,400 milliamp-hour (mAh) battery. (By comparison, Apple's Smart Battery Case has 1,877 mAh.) There is no microUSB version of the wallet, at least not yet.
